Page 11: Acl Accelerate
ACL acceleration uses memory. To achieve the best trade-off between memory and ACL processing performance, H3C recommends you enable ACL acceleration for large ACLs. For example, when you use a large ACL for a session-based service, such as NAT or ASPF, you can enable ACL acceleration to avoid session timeouts caused by ACL processing delays.

This keyword is not available on an SAP interface card working in bridge mode. Matches DSCP values. The dscp-list argument is a list dscp dscp-list of up to 8 DSCP values.
Page 43 NOTE: The match criteria listed below must be unique in a class that uses the AND operator. To ensure that the class can be successfully applied to interfaces, avoid defining multiple if-match clauses for these match 8021p-list criteria or inputting multiple values for any of the list arguments, such as the argument.
Page 44 Defining a criterion to match a source MAC address You can configure multiple source MAC address match criteria for a class. A criterion to match a source MAC address is significant only to Ethernet interfaces. Defining the relationships between match criteria This subsection describes how to use both AND and OR operators to define the match relationships between the criteria for a class.

undo cir View FR class view Default level 2: System level Parameters committed-information-rate: Minimum CIR in bps, which ranges from 1000 to 45000000. The CIR is 56000 bps by default. Description Use the cir command to set CIR for FR PVCs. Use the undo cir command to restore the default.

committed-information-rate: CIR ALLOW in bps, which ranges from 1000 to 45000000. The CIR ALLOW is 56000 bps by default. Description Use the cir allow command to set the CIR ALLOW for FR PVCs. Use the undo cir allow command to restore the default. CIR ALLOW is the transmit rate that an FR PVC can provide when no congestion occurs to the network.

performed for packets of PVCs as follows: dropping the FR packets with the DE flag bit 1, and setting the BECN flag bits and FECN flag bits of FR packets to 1. Related commands: fr congestion-threshold. Examples # Create an FR class test1 and configure the FR network to drop FR packets with the DE flag bit 1 when the current PVC queue length uses more than 80% of the total PVC queue length.

This argument ranges from 1 to 1024 and defaults to 40. Description Use the fifo queue-length command to set the FIFO queue length for FR PVCs.
Page 156: Fr Congestion-Threshold
By default, no FR class is created. The FR class parameters do not take effect until you associate the FR class with an interface or PVC and enable the FR QoS function on the interface. With an FR class removed, all the associations associating this FR class with an interface or a DLCI are released.

Description Use the fr del inbound-interface command to configure an interface-based DE rule list. Before the incoming packets of the specific interfaces are to be forwarded as FR packets, the DE flag bits of these packets are set to 1.

greater-than bytes: IP packets with the length greater than the bytes argument. The bytes argument ranges from 0 to 65535. less-than bytes: IP packets with the length less than the bytes argument. The bytes argument ranges from 0 to 65535. tcp ports: IP packets with the source or destination TCP port number as the ports argument.
Page 160: Fr Traffic-Shaping
Description Use the fr traffic-policing command to enable FR traffic policing. Use the undo fr traffic-policing command to disable FR traffic policing. FR traffic policing is applicable only to the ingress interfaces on the DCE side of an FR network. Before enabling traffic policing for the incoming interfaces, make sure that FR switching is globally enabled on the DCE by using the fr switching command.

undo fragment [ data-level | voice-level ] View FR class view Default level 2: System level Parameters fragment-size: Fragment size, which ranges from 16 bytes to 1600 bytes. This argument is 45 bytes by default. Description Use the fragment command to enable the packet fragmentation function (conforming to frame relay forum’s FRF.12) for FR PVCs.
Page 162: Traffic-Shaping Adaptation
Instead of removing an FR class, the undo fr-class command just cancels the association between the FR class and the current FR PVC or interface. Use the undo fr class command to remove an FR class. For an interface associated with an FR class, all the PVCs on the interface inherit the FR QoS parameters in the FR class.
